0012631: [Regression] Font selection in the 'Tool' tab of the Document Setup is being ignored by Scribus

Description

A feature that used to work reliably in 1.3.3.x ceased to work somewhere along the way to 1.4.4, namely the default font choice for text. Scribus stubbornly refuses to apply another font choice than the original default font.

Steps To Reproduce

1) Create a new doc.

2) Insert a text frame.

3) Insert text.

4) Go to File > Document Setup and change the default font in the Tools section.
